Mendelian Genetics help! I am trying to understand this process so any explanation you can offer would help.?

uming that a male/female pair are heterozygous (Genotype Rr) for two characteristics, and those traits are tongue rolling (RR, Rr, and rr) and blood type (genotype MN). Both are phenotypically tongue rollers. Likewise, both male and female had type MN blood. What is the genotypes of the male and female? What kind of games would the male/female produce. What genotypes and phenotypes could appear among the offspring of this couple and in what ratio?
